Potty training help! Where to begin??

Amanda

I feel so confused. My son is not potty trained yet. His doctor says potty training doesn't usually start till 3 years old but I've read countless articles that say otherwise. His friend was potty trained at 2. I don't know what is right. I've tried this year potty training but its been met with resistance. He doesn't like pulling his pants and diaper down so he only sat on his potty a few times with his pants on. Now whenever I try to lead him to the potty he refuses. He will be 3 next month. Please give me pointers, advice, anything!!
